Original No. 1,603,606, dated October 19, 1926, Serial No. 660,905,filed September 4, 1923. Application for reissue filed `November 12,1926. Serial No. 148,308.

This invention relates to draft rigging for railway cars and,particularly stated, involves the production of a comparatively simplesingle key draft gear construction.

An object of the present invention is to provide a strong and reliabledraft rigging in which a plurality of flanged members are employed anddisposed at the respective ends'of the draft rigging pocket forreceiving the draft and bufling strains, said members being arranged soas to bridge and tie the draft sills to which latter they are connectedat a plurality of points by advantageously disposed rivets Anotherobject of the invention resides in the provision of a draft riggingembodying a key adapted to slidably connectv the coupler and yoke, andcooperating flanged stop members or castings, two of said castingsproviding relatively strong but light weight front stop members arrangedabove l and below the yoke and coupler and designed to receive the draftstrains, the other of said castings being arranged at the rear of saidyoke and adapted to receive the buifing strains, both the draft andbufling strains being imparted through a cushioning mechanism preferablyof the friction spring type suitably contained within the draft rigging.

A further object of the invention is to provide a railway draft rigging0f durable construction in which the anged members forming the frontstop members and providing vertically alined stop faces, are formed withattaching flanges which are longitudinally offset but of substantiallythe same relative strength value whereby a similar number of connectingrivets can be advantageously employed without interfering with the otherassociated elements of the draft rigging, such as the striking casting,for example.

A still further object of the present invention is to provide a railwaydraft rigging in which the lower front stop member, in addition topresenting a transversely disposed T-shaped reinforced wall adapted toreceive the draft strains the full width of the draft rigging pocket, isalso provided with a horizontal flange which acts to reinforce said walland also provides a support yfor the inner end of the coupler stem.

The invention further consists in the combination and arrangement `ofthe several parts which will be hereinafter described.

In the drawings illustrating an embodiment of my invention, the scopewhereof is set forth in the claims Figure 1 is a t-op plan view of arailway draft rigging embodying my invention, a portion of said figurebeing shown in horizontal section.

Figure 2 is a vertical longitudinal sectional view. v

Referring to the drawings in which corresponding reference charactersdesignate similar parts in the several views, 1-1 designate the carcenter or draftl sills, 2 the end framing, 3 the striking casting towhich the end framing is connected by means of the angle member 4, and 5the cover plate. A coupler carrying iron 6 is shown attached to thedraft sills.

The coupler 7 is connected to the yoke member 8 by means of atransversely extending key 9, said key passing through suitable slots 10provided in the yoke arms and registering slots 11 formed in the draftsills. Interposed between the rear end of vthe coupler and the closed orlooped end of the yoke is t-he cushioning mechanism or draft gear'proper, which may comprise a friction barrel having a follower portion12, shown as cooperating with the front stop member and a series ofwedging blocks 13 and a wedge block 14, the latter being adapted tocontact a suit-able filler block 15 connected to the inner face of therear end of the yoke. It is to be understood that the particular form ofcushioning mechanism illustrated, while advantageously included with mypresent design of draft rigging, is capable of change and modification,and I do notwish to be understood as limiting the invention to the exacttype disclosed.

The cushioning mechanism is maintained in position between the yoke armsand in alinement with the coupler and the backstop member of the draftrigging by means of a pair of straps or draftv gear supporting.

members 16 and 17, said mechanism bein connected to the lower flanges ofthe dra t sills by means of bolts 18.

The draft gear is adapted to be received into a draft rigging pocketformed between theV draft sills and a plurality of anged membersarranged to bridge and tie vthe draft sills at the frontand rear ends ofthe pable of beingv economically manufactured` and provided withadvantageously located reinforcing webs or ribs, all as will hereinafter appear in connection with the-descriptionofeach member now to begiven.

The rear member or backstop 19 is provided With sidewalls 20 eachofwhich is formed with a plurality of openings adapted toA receivey rivets21` which firmly connect the member to the draft sills. The side wallsareprovided with portions projecting aboveA and below the planes of the'remaining' portions, and connected to these project-ing portionsare thereinforcing ribs 22 which unite the sidel walls totheI horizontal lydisposed web 23 of the backstop.V The side walls are united by thehorizontally 'disposed web 23, and also by the front endwall 24andafrearwall 25, said horizontal web 23 alsov servingto lunitetherespective end` walls longitudinally of' the casting. The respectiveend-walls are also-reinforced and united by a; vertically disposed web26 which intersects Vthe-horizontal web 23 and has portions thereofextending above and below the same, as shown; Reinforcing webs 27 areprovided for the front or buliing wall 24, said webs being angularlydisposed with relation to the vertical web 26 and designedto-termi'nate'short of the side walls and rear end wall. Ribs 28 mayAalso be provided to unite the endsV ofthe side walls with the rear endwall; .The backstop rigidly con nectsv thev spaced draft sills, andwhile of comparatively simpleconstruction, itpresents anadequatelyreinforced buliing wall capable of effectively receiving the buiiingloads incidentA to serviceconditions. The

:upper front stopl member 29 bridges the draft sills and is locatedabovet-heyoke` and coupler stem, said member being provided withA sidelwalls 30 formed with suitable openings. adapted to receive rivet-s 31for` or wafllf32 extends transversely ofthe draft rigging;l pocket andunites'theside walls 30,

said web providing a front stop face cooperatively associated withtheeforward end= of the cushioning mechanism; They verticalE web 32 isprovided with ai transversely ar'- ranged and forwardly extendingreinforcing flange 33. There are also provided vertically disposed andangularly arrangedk reinforcing ribs 34 extending from the front stopwall 32, said ribs uniting the horizontal web 35 of the front stopmember with said wall. A vertically and transversely disposed flange 36is formed on, the ,forward end of the horizontal web 35, said flange andstop wall being further united to each other andi tothe horizontal webby means of a centrally located and vertically dise posed longitudinalweb 37. The portionof the side-walls whichv extendsrearwardly of thestop wall 32-is preferably united with said'iwall by webs 38.V A:maximum riveting area isv obtained for rigidly connecting the stopmembers to the spaced draft sills as the result `of this construction,saidarea beingx equal to the riveting area of the lower. front stop4member now to be described. The front rivets 31 also preferably extend.through the vertical longitudinal flanges or webs ofthe striking casting3. Y Y

rEhe-lower front stop member has a T-end providing a stop face formed bythe transversely arranged vertically. extending wall 39, said stop facebeing disposed in vertical alinementwith the stop face formed on thewall off the upper front stop member., The wall? 39 is reinforced by aplurality of ver'-A tically disposed ribs 40, some of said ribs beingarranged at an angle tof the centrally located vertical reinforcing rib41`` A hori-Y zontally arranged web 42 also reinforces the frontstopwall 39, said web comprising thc main body portion ofthe casting andbeing` provided with laterally extending portions 43 adapted to underliethe lower flanges of the draftsill's to which they are connected by aseries of rivets 44. In the construction of the lower front stop member.allof the attaching rivets are located forwardly ofthe front stop wall39, this being made possible by the relatively greatdistanceprovidedbe-y tween the coupler carrying ironandcushion: ingmechanism. It will also be observed that the rivets are disposed:vertically, and in passing through the lower horizontal. flange of thedraft channelsprovide ak very rigid construction equalin strengthto theupper front stop member' and its attaching means.

The-main horizontal web 42.is preferably provided at its forward endwith a vertical transversely disposed flange 45, said flange projectingabove and y below the web, asy shown. The outermost longitudinallyV air-Y ranged` reinforming ribsf are continued beyond' the verticalk flange45 to. substantially the endsLof the lateral extension 43. Angu larshaped flanges. 46 may berprovided for" uniting the vertical flangeswith the lateral extension 43.

ico

Arranged adjacent the upper edge of the front wall 39 is a forwardlyextending web or flange 47, said flange extending transversely of thestop member and acting to support the rear end of the coupler and alsothe forward end of the yoke, which latter projects between thesuperposed front stop members. The upright ribs 40 are'adapted tointersect the forward edge of the web 47 and extend beneath the ysamefor reinforcing it. The upper surface of the supporting flange or web 47is disposed substantially in the same horizontal plane as the upper faceof the carry iron, as best shown in Figure 2. The front wall 39 may becontinued beneath the horizontal web 42 to receive the full contact ofthe adjacent portion of the cushioning mechanism.

A draft rigging constructed in accordance witli'my present inventionprovides a very strong structure which can be contained within avrelatively limited space, the respective stop members, in addition tofunctioning with the cooperating part of the cushioning mechanism, alsoacting to greatly strengthen the construction by reason of the bridgingand tying the sills.
